Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of stranding devices, specifically relating to a copper wire concentric stranding device. Background Technology
[0002] Concentric stranding of copper wire is a typical stranding process used in high-end conductor manufacturing, communication cable construction, and the internal conductor composition of electrical cables. It involves simultaneously stranding one or more center wires with several outer wires, resulting in a stranded conductor with excellent conductivity, flexibility, and mechanical strength. In actual production, to ensure the stranding effect, it is essential to guarantee high alignment accuracy, good cleanliness, and stable strand pitch consistency of the wires during stranding. Therefore, as a key piece of equipment affecting product quality, the sophistication of the stranding equipment's structural design directly relates to the process control capabilities of copper wire stranding.
[0003] Before stranding, the surface of the wire is easily contaminated with impurities such as dust, metal shavings, and oil particles during processing, transportation, and storage. Traditional copper wire concentric stranding equipment usually only has the function of stranding the wire and lacks the function of pre-cleaning the wire at the front end. As a result, dust, oil, metal shavings and other impurities in this part are easily drawn into the gaps between the wires during the stranding process. They are difficult to remove in the cleaning process such as pickling after stranding, forming a potential source of pollution and affecting the conductor performance. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a copper wire concentric stranding device that can effectively clean the wire before stranding, ensuring the wire is in a relatively clean state before stranding. This improves the problem that after stranding, some dirt and impurities are trapped between the central and outer wires and are difficult to remove in subsequent cleaning processes, affecting cable performance. Since a cleaning is completed before stranding, it also reduces the time and cost required for cleaning treatments such as acid washing after stranding.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper wire concentric stranding device, comprising a cleaning function stranded wire drum mechanism, the cleaning function stranded wire drum mechanism comprising a base, a support column at the top of the base, an mounting cylinder at the top of the support column, a first stranded wire drum and a second stranded wire drum rotatably mounted on the inner side of the mounting cylinder via a sealed bearing, a first connecting rod connecting the first stranded wire drum and the second stranded wire drum, a through-hole being provided between the inner and outer sides of the mounting cylinder, and a closing door plate hinged to the inner side of the through-hole, the first stranded wire drum and the second stranded wire drum... An adaptive cleaning brush mechanism is connected between the two parts. The adaptive cleaning brush mechanism includes a fixed plate fixed between the first and second stranded wire drums. A guide rod is connected to one side of the fixed plate. The guide rod passes through two sliding plates and is slidably connected to them. The first and second cleaning brushes are screwed onto the sides of the two sliding plates that are close to each other, respectively. A limit plate is screwed to one end of the guide rod. A spring is sleeved on the outside of the guide rod. A suction hood is connected to the bottom of the mounting cylinder. A negative pressure pipe is connected to the bottom of the suction hood. The other end of the negative pressure pipe is connected to an industrial vacuum cleaner.
[0006] The beneficial effects of this utility model are as follows: During the operation of this device, after closing the sealed door panel and turning on the industrial vacuum cleaner, negative pressure suction is applied to the enclosed space between the first and second stranded wire drums through the negative pressure pipe and suction hood. As the wire passes through the adaptive cleaning brush mechanism between the first and second stranded wire drums, the sliding plate is pushed by the spring force, allowing the second and first cleaning brushes to remain in close contact. This mechanism adapts to the wire diameter and automatically compensates for wire fluctuations during operation, maintaining contact between the second and first cleaning brushes and the wire. The close friction between the wire and the first and second cleaning brushes, which have an adaptive floating function, removes dust, metal shavings, oil particles, and other contaminants from the wire surface. The removed impurities are then sucked into the storage chamber of the industrial vacuum cleaner by negative pressure, ensuring that the wire is in a relatively clean state before stranding. This improves the problem that after stranding, some dirt and impurities are trapped between the central and outer wires and are difficult to remove in subsequent cleaning processes, affecting cable performance. Since a cleaning is completed before stranding, the time and cost required for cleaning treatments such as acid washing after stranding are also reduced.
[0007] To observe the enclosed space between the first and second stranded wire spools:
[0008] As a further improvement to the above technical solution: an acrylic observation window is provided in the middle section of the closed door panel.
[0009] The beneficial effect of this improvement is that the acrylic observation window can be used to observe the enclosed space between the first and second stranded coils after the closed door panel is closed.
[0010] In order to filter the airflow:
[0011] As a further improvement to the above technical solution: a filter channel is connected to the top of the closed door panel, and a filter cotton filter element is provided inside the filter channel.
[0012] The beneficial effects of this improvement are as follows: the filter channel serves as the channel for external airflow to enter when the industrial vacuum cleaner performs negative pressure suction in the enclosed space between the first and second coils, so as to balance the internal and external pressure and enable the industrial vacuum cleaner to perform suction smoothly. Through the setting of the filter cotton filter element, the airflow can be filtered to prevent dust from entering.
[0013] To ensure that each wire is clean before stranding:
[0014] As a further improvement to the above technical solution: a center wire threading hole and an outer wire threading hole are provided through both ends of the first and second stranded wire drums, and the adaptive cleaning brush mechanism is provided in a set between the center wire threading holes of the first and second stranded wire drums and between the outer wire threading holes located on the same axis.
[0015] The beneficial effects of this improvement are as follows: the center wire passes through the center wire hole of the first stranded drum and the second stranded drum in sequence, and the outer wire is correspondingly inserted into the outer wire hole, ensuring that each group of wires is located between the first cleaning brush and the second cleaning brush of the adaptive cleaning brush mechanism, thereby ensuring that each wire can be cleaned before stranding.
[0016] As a further improvement to the above technical solution: one end of the first stranded drum is connected to a second connecting rod, one end of the second connecting rod is connected to the wire feeding mechanism, a frame is provided on one side of the cleaning function stranded drum mechanism, a stranded wire seat is installed on the top of the frame, and a pressing guide mechanism and a winding device are installed on the top of the frame.
[0017] As a further improvement to the above technical solution: the wire feeding mechanism includes a wire feeding mechanism bracket connected to the second connecting rod. A gear ring is provided on the outer side of one end of the wire feeding mechanism bracket. The gear ring meshes with a gear. The gear is connected to the output end of the first motor. The first motor is fixedly installed on the top of the motor base. Multiple sets of outer layer wire feeding mechanisms are distributed in a ring on the outer side of the wire feeding mechanism bracket. A central wire feeding mechanism is installed on the inner side of the wire feeding mechanism bracket.
[0018] When the stranding begins, the first motor drives the gear to rotate, thereby driving the gear ring together with the outer wire stranding mechanism on the wire stranding mechanism bracket, while the fixing frame of the center wire stranding mechanism remains fixed, the center wire remains in the center position, and the outer wire forms a spiral strand around the center wire.
[0019] As a further improvement to the above technical solution: the outer wire feeding mechanism includes a first spool mounting frame installed on the outside of the feeding mechanism support, and the central wire feeding mechanism includes a fixed frame rotatably installed on the inside of the feeding mechanism support. The bottom end of the fixed frame is fixed to the ground, and a first spool mounting frame is also fixed on one side of the fixed frame. A first spool mounting shaft is rotatably installed on the inside of the first spool mounting frame. A threaded section is provided on the outside of one end of the first spool mounting shaft. A first limiting plate is fixedly sleeved on the outside of the first spool mounting shaft, and a second limiting plate is slidably installed. A spiral positioning block is threadedly connected to the outside of the first spool mounting shaft through the threaded section. A wire frame is installed at the bottom of the first spool mounting frame of the outer wire feeding mechanism. A coil assembly is provided on the bottom of the first spool mounting frame of the outer wire feeding mechanism and on the first spool mounting frame of the central wire feeding mechanism.
[0020] When using this device, the operator first places the spool with the center wire wound on it horizontally in the center wire feeding mechanism inside the feeding mechanism bracket, so that the first spool mounting shaft passes through the center hole of the spool and is axially positioned by the first limiting plate at the shoulder of the shaft. The second limiting plate is then inserted and slidably moved to the end face of the spool, aligned with the first spool mounting shaft. The spiral positioning block is then aligned with the tightening thread section, screwed in, and tightened to ensure that the wire spool does not move axially. The outer layer wire spools are then installed in the same way in the outer layer wire feeding mechanism distributed in a ring on the outside of the feeding mechanism bracket. When the feeding mechanism bracket rotates, the fixing frame of the center wire feeding mechanism remains fixed.
[0021] To guide and limit the movement of the wire:
[0022] As a further improvement to the above technical solution: the conductor frame includes two square fixing blocks, and two circular conductor limiting rods are connected between the two square fixing blocks. One of the square fixing blocks is connected and fixed to the first spool mounting frame of the outer wire feeding mechanism.
[0023] The beneficial effects of this improvement are as follows: After the outer wire reel is installed, the end of the outer wire is passed between the two circular wire limiting rods of the conductor frame and guided to the conductor coil assembly. The two circular wire limiting rods limit the wire while preventing it from being scratched.
[0024] To compress and guide the stranded wires:
[0025] As a further improvement to the above technical solution: the clamping guide mechanism includes a mounting vertical plate installed on the frame, an electric cylinder mounting plate installed on the top of the mounting vertical plate, a first electric cylinder installed on the top of the electric cylinder mounting plate, a sliding groove passing through the front and rear sides of the mounting vertical plate and a lifting slider slidably installed thereon, the piston rod end of the first electric cylinder being connected to the lifting slider, a lower clamping guide wheel rotatably installed on one side of the mounting vertical plate, and an upper clamping guide wheel rotatably installed on one side of the lifting slider.
[0026] The beneficial effects of this improvement are as follows: After the stranded wire passes through the stranding seat, it enters between the lower clamping guide wheel and the upper clamping guide wheel. Then, the first electric cylinder of the clamping and guiding mechanism is activated, driving the lifting slider to move down along the mounting vertical plate groove, so that the upper clamping guide wheel and the lower clamping guide wheel are engaged, thereby clamping and guiding the stranded wire.
[0027] In order to wind up the stranded wire:
[0028] As a further improvement to the above technical solution: the winding device includes a second spool mounting frame fixed on the frame, a second motor mounted on one side of the second spool mounting frame, the output end of the second motor connected to the second spool mounting shaft, a first limiting block sleeved on the outer side of the second spool mounting shaft, a second electric cylinder mounted on the other side of the second spool mounting frame, the piston rod end of the second electric cylinder connected to a third spool mounting shaft, and a second limiting block sleeved on the outer side of the third spool mounting shaft.
[0029] The beneficial effects of this improvement are as follows: When installing the take-up spool, one end of the take-up spool is fitted onto the outside of the second spool mounting shaft. The second electric cylinder is activated to push the third spool mounting shaft to move axially and insert it into the other end of the take-up spool, so that the first limit block and the second limit block clamp the end face of the take-up spool. During the winding action, the second motor is controlled to drive the take-up spool to rotate and wind up the stranded wire.

Detailed Implementation
[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0047] like Figure 1-14As shown, a copper wire concentric stranding device includes a cleaning function stranded wire drum mechanism 1. The cleaning function stranded wire drum mechanism 1 includes a base 2, a support column 3 on the top of the base 2, and an mounting cylinder 4 on the top of the support column 3. A first stranded wire drum 6 and a second stranded wire drum 7 are rotatably mounted on the inner side of the mounting cylinder 4 via a sealed bearing 5. A first connecting rod 8 connects the first stranded wire drum 6 and the second stranded wire drum 7. An opening is provided between the inner and outer sides of the mounting cylinder 4, and a closing door plate 9 is hinged to the inner side of the opening. An adaptive cleaning brush mechanism 15 connects the first stranded wire drum 6 and the second stranded wire drum 7. The brush cleaning mechanism 15 includes a fixing plate 16 fixed between the first stranded coil 6 and the second stranded coil 7. A guide rod 18 is connected to one side of the fixing plate 16. The guide rod 18 passes through two sliding plates 19 and is slidably connected to them. A first cleaning brush 17 and a second cleaning brush 20 are screwed to the sides of the two sliding plates 19 that are close to each other, respectively. A limit plate 21 is screwed to one end of the guide rod 18. A spring 22 is sleeved on the outside of the guide rod 18. A suction hood 23 is connected to the bottom of the mounting cylinder 4. A negative pressure pipe 24 is connected to the bottom of the suction hood 23. The other end of the negative pressure pipe 24 is connected to an industrial vacuum cleaner 25.
[0048] During operation of this device, after closing the sealing door 9, the industrial vacuum cleaner 25 is turned on. The vacuum cleaner uses the negative pressure pipe 24 and suction hood 23 to perform negative pressure suction on the enclosed space between the first and second stranded wire drums 6 and 7. As the wire passes through the adaptive cleaning brush mechanism 15 between the first and second stranded wire drums 6 and 7, the sliding plate 19 is pushed by the spring force of the spring 22, allowing the second cleaning brush 20 and the first cleaning brush 17 to remain tightly close together. This mechanism adapts to the wire diameter and automatically compensates for wire fluctuations during operation via the spring 22, maintaining proper contact between the second cleaning brush 20 and the first cleaning brush 17 and the wire. Through close contact and the friction between the wire and the first cleaning brush 17 and the second cleaning brush 20, which have an adaptive floating function, dust, metal shavings, oil particles and other contaminants on the surface of the wire are brushed off. The cleaned impurities are then sucked into the storage chamber of the industrial vacuum cleaner by negative pressure, so that the wire is in a relatively clean state before stranding. This improves the problem that after the cable is stranded, some dirt and impurities are trapped between the central wire and the outer wire and are difficult to be cleaned in subsequent cleaning processes, which affects the performance of the cable. Since a cleaning is completed before stranding, the time and cost required for cleaning treatments such as acid washing of the cable after stranding are also reduced.
[0049] An acrylic observation window 10 is provided in the middle section of the closed door panel 9.
[0050] The acrylic observation window 10 can be used to observe the enclosed space between the first strand 6 and the second strand 7 after the closed door panel 9 is closed.
[0051] The top of the closed door panel 9 is connected to a filter channel 11, and the filter channel 11 is provided with a filter cotton filter element 12.
[0052] The filter channel 11 serves as the channel through which external airflow enters when the industrial vacuum cleaner 25 performs negative pressure suction in the enclosed space between the first coil 6 and the second coil 7, so as to balance the internal and external pressure and enable the industrial vacuum cleaner 25 to perform suction smoothly. The filter cotton filter element 12 can filter the airflow and prevent dust from entering.
[0053] Both ends of the first stranded wire drum 6 and the second stranded wire drum 7 are provided with a center wire hole 13 and an outer wire wire hole 14. The adaptive cleaning brush mechanism 15 is provided with a set between the center wire hole 13 of the first stranded wire drum 6 and the second stranded wire drum 7 and between the outer wire wire hole 14 located on the same axis.
[0054] The center wire passes through the center wire hole 13 of the first stranded wire drum 6 and the second stranded wire drum 7 in sequence, and the outer wire is passed through the corresponding outer wire hole 14. This ensures that each group of wires is located between the first cleaning brush 17 and the second cleaning brush 20 of the adaptive cleaning brush mechanism 15, thereby ensuring that each wire can be cleaned before stranding.
[0055] One end of the first stranded wire drum 6 is connected to a second connecting rod 26, and one end of the second connecting rod 26 is connected to the wire feeding mechanism. A frame is provided on one side of the cleaning function stranded wire drum mechanism 1, and a stranded wire seat 42 is installed on the top of the frame. A pressing guide mechanism and a winding device 49 are installed on the top of the frame.
[0056] The wire feeding mechanism includes a wire feeding mechanism bracket 27 connected to the second connecting rod 26. A gear ring 58 is provided on the outer side of one end of the wire feeding mechanism bracket 27. The gear ring 58 meshes with a gear 59. The gear 59 is connected to the output end of the first motor 28. The first motor 28 is fixedly installed on the top of the motor base 29. Multiple sets of outer layer wire feeding mechanisms 30 are distributed in a ring on the outer side of the wire feeding mechanism bracket 27. A center wire feeding mechanism 31 is installed on the inner side of the wire feeding mechanism bracket 27.
[0057] When the stranding begins, the first motor 28 drives the gear 59 to rotate, thereby driving the gear ring 58 together with the outer wire feeding mechanism 30 on the wire feeding mechanism bracket 27, while the fixing frame 57 of the center wire feeding mechanism 31 remains fixed, the center wire remains in the center position, and the outer wire forms a spiral strand around the center wire.
[0058] The outer wire feeding mechanism 30 includes a first spool mounting bracket 32 installed on the outside of the feeding mechanism support 27. The central wire feeding mechanism 31 includes a fixed bracket 57 rotatably installed on the inside of the feeding mechanism support 27. The bottom end of the fixed bracket 57 is fixed to the ground. The first spool mounting bracket 32 is also fixed on one side of the fixed bracket 57. A first spool mounting shaft 33 is rotatably installed on the inside of the first spool mounting bracket 32. A threaded section 34 is provided on the outside of one end of the first spool mounting shaft 33. A first limiting plate 35 is fixedly sleeved on the outside of the first spool mounting shaft 33 and a second limiting plate 36 is slidably installed. A spiral positioning block 37 is threadedly connected to the outside of the first spool mounting bracket 32 of the outer wire feeding mechanism 30 through the threaded section 34. A wire frame 38 is installed at the bottom of the first spool mounting bracket 32 of the outer wire feeding mechanism 30. A coil assembly 41 is provided on the bottom of the first spool mounting bracket 32 of the outer wire feeding mechanism 30 and on the first spool mounting bracket 32 of the central wire feeding mechanism 31.
[0059] When using this device, the operator first places the spool with the center wire wound on it horizontally in the center wire feeding mechanism 31 inside the feeding mechanism bracket 27, so that the first spool mounting shaft 33 passes through the center hole of the spool and is axially positioned by the first limiting plate 35 at the shoulder. The second limiting plate 36 is then inserted and slidably moved to the end face of the spool, aligned with the first spool mounting shaft 33. The spiral positioning block 37 is then screwed in and tightened after being aligned with the tightening thread section 34 to ensure that the wire spool does not move axially. The outer layer wire spool is then installed in the outer layer wire feeding mechanism 30 distributed in a ring on the outside of the feeding mechanism bracket 27 in the same way. When the feeding mechanism bracket 27 rotates, the fixing frame 57 of the center wire feeding mechanism 31 remains fixed.
[0060] The conductor frame 38 includes two square fixing blocks 39, and two circular conductor limiting rods 40 are connected between the two square fixing blocks 39. One of the square fixing blocks 39 is connected and fixed to the first spool mounting frame 32 of the outer wire feeding mechanism 30.
[0061] After the outer wire reel is installed, the end of the outer wire is passed through the two circular wire limiting rods 40 of the wire frame 38 and guided to the wire coil group 41. The two circular wire limiting rods 40 limit the wire while preventing it from being scratched.
[0062] The clamping guide mechanism includes a mounting vertical plate 43 mounted on a frame. An electric cylinder mounting plate 44 is mounted on the top of the mounting vertical plate 43. A first electric cylinder 45 is mounted on the top of the electric cylinder mounting plate 44. A sliding groove runs through the front and rear sides of the mounting vertical plate 43, and a lifting slider 46 is slidably mounted thereon. The piston rod end of the first electric cylinder 45 is connected to the lifting slider 46. A lower clamping guide wheel 47 is rotatably mounted on one side of the mounting vertical plate 43. An upper clamping guide wheel 48 is rotatably mounted on one side of the lifting slider 46.
[0063] After the stranded wire passes through the stranding seat 42, it enters between the lower clamping guide wheel 47 and the upper clamping guide wheel 48. Then, the first electric cylinder 45 of the clamping and guiding mechanism is activated, driving the lifting slider 46 to move down along the slide groove of the mounting vertical plate 43, so that the upper clamping guide wheel 48 and the lower clamping guide wheel 47 are engaged, and the stranded wire is clamped and guided.
[0064] The winding device 49 includes a second spool mounting bracket 50 fixed on the frame. A second motor 51 is mounted on one side of the second spool mounting bracket 50. The output end of the second motor 51 is connected to a second spool mounting shaft 52. A first limiting block 53 is sleeved on the outer side of the second spool mounting shaft 52. A second electric cylinder 54 is mounted on the other side of the second spool mounting bracket 50. The piston rod end of the second electric cylinder 54 is connected to a third spool mounting shaft 55. A second limiting block 56 is sleeved on the outer side of the third spool mounting shaft 55.
[0065] When installing the take-up spool, one end of the take-up spool is fitted onto the outside of the second spool mounting shaft 52. The second electric cylinder 54 is activated to push the third spool mounting shaft 55 to move axially and insert it into the other end of the take-up spool, so that the first limiting block 53 and the second limiting block 56 clamp the end face of the take-up spool. During the winding action, the second motor 51 is controlled to drive the take-up spool to rotate and wind up the stranded wire.
[0066] The working principle and usage process of this utility model are as follows: When using this device, the operator first places the spool with the center wire wound on it horizontally in the center wire feeding mechanism 31 inside the feeding mechanism bracket 27, so that the first spool mounting shaft 33 passes through the center hole of the spool and is axially positioned by the first limiting plate 35 at the shoulder of the shaft. Then, the second limiting plate 36 is aligned with the first spool mounting shaft 33, inserted, and slidably moved to the end face of the spool. Finally, the spiral positioning block 37 is aligned with the tightening thread section 34 and screwed in. Tighten to ensure no axial movement of the wire coil, and install the outer wire coil in the outer wire feeding mechanism 30 distributed in a ring outside the wire feeding mechanism bracket 27 in the same way. After repeating the fixing steps of the center wire coil, pass the end of the outer wire between the two circular wire limiting rods 40 of the conductor frame 38 and guide it to the conductor coil group 41, and pass it through the conductor coil group 41. Then guide the end of the center wire through the conductor coil group 41 to limit the wire entry path.
[0067] Then, open the closed door panel 9 of the cleaning function coil mechanism 1, and pass the center wire through the center wire threading hole 13 of the first coil 6 and the second coil 7 in sequence. Then, pass the outer layer wire through the corresponding outer layer wire threading hole 14, ensuring that each group of wires is located between the first cleaning brush 17 and the second cleaning brush 20 of the adaptive cleaning brush mechanism 15. Fit one end of the take-up coil onto the outside of the second coil mounting shaft 52, and start the second electric cylinder 54 to push the third coil mounting shaft 55 to move axially and insert it into the other end of the take-up coil, so that the first limit block 53 and the second limit block 56 clamp the end face of the take-up coil, completing the preparation work.
[0068] At the start of stranding, the PLC control system synchronizes the winding speed with the unwinding speed, activating the first motor 28 and the second motor 51. The first motor 28 drives the gear 59 to rotate, thereby causing the gear ring 58 and the unwinding mechanism bracket 27 to rotate, while the fixed frame 57 remains stationary. The rotation of the unwinding mechanism bracket 27 also drives the second connecting rod 26 and the first stranding drum 6 to rotate. Simultaneously, the rotation of the first stranding drum 6 drives the rotation of the second stranding drum 7 via the first connecting rod 8, thereby causing the outer layer wire to rotate around the center wire. The center wire remains in the center position, and the outer layer wire and the center wire rotate around the center wire. After the core wire passes through the second stranding drum 7, the outer layer of wire forms a spiral strand around the core wire between the second stranding drum 7 and the stranding seat. The stranded wire passes through the stranding seat 42 and enters between the lower clamping guide wheel 47 and the upper clamping guide wheel 48. Then, the first electric cylinder 45 of the clamping and guiding mechanism is activated, driving the lifting slider 46 to move down along the groove of the mounting vertical plate 43, so that the upper clamping guide wheel 48 and the lower clamping guide wheel 47 engage to clamp and guide the stranded wire. Finally, the second motor 51 of the winding device 49 drives the winding drum to rotate and wind up the stranded wire.
[0069] During operation of this device, after closing the sealing door 9, the industrial vacuum cleaner 25 is turned on. The vacuum cleaner uses the negative pressure pipe 24 and suction hood 23 to perform negative pressure suction on the enclosed space between the first and second stranded wire drums 6 and 7. As the wire passes through the adaptive cleaning brush mechanism 15 between the first and second stranded wire drums 6 and 7, the sliding plate 19 is pushed by the spring force of the spring 22, allowing the second cleaning brush 20 and the first cleaning brush 17 to remain tightly close together. This mechanism adapts to the wire diameter and automatically compensates for wire fluctuations during operation via the spring 22, maintaining proper contact between the second cleaning brush 20 and the first cleaning brush 17 and the wire. Through close contact and the friction between the wire and the first cleaning brush 17 and the second cleaning brush 20, which have an adaptive floating function, dust, metal shavings, oil particles and other contaminants on the surface of the wire are brushed off. The cleaned impurities are then sucked into the storage chamber of the industrial vacuum cleaner by negative pressure, so that the wire is in a relatively clean state before stranding. This improves the problem that after the cable is stranded, some dirt and impurities are trapped between the central wire and the outer wire and are difficult to be cleaned in subsequent cleaning processes, which affects the performance of the cable. Since a cleaning is completed before stranding, the time and cost required for cleaning treatments such as acid washing of the cable after stranding are also reduced.
